So just a little background...I have been using AcneFree Severe by University Medical for years now. It has 10% bp...and my skin has had no real irritations for a long time from it. Well I think they stopped making it until the new year and I haven't been able to find it anywhere so I decided to give Dan's products a try...well I washed my face a little while ago and used the bp and now my face is burning like crazy. I don't understand if I had been using 10% prior and now down to 2.5% why there would be irritation. I used my own regular moisturizer but my skin hasn't calmed down at all. Any ideas what's going on?
